Hi, is there a way of setting eth parameters for hypervisors? My freebsd
instance has terrible performance when these are enabled. Currently I
run these on all hypervisors manually.
ethtool –K vnet0 gro off
ethtool –K vnet2 gro off
ethtool –K vnet0 lro off
ethtool –K vnet2 lro off

Hi Ernest,
we have similar issues with IPoIB. To fix it we use VDSM hooks:
# cat /usr/libexec/vdsm/hooks/before_vdsm_start/network.sh
...
ethtool -K ib0 tso off 2>/dev/null
ethtool -K ib1 tso off 2>/dev/null
...
Nevertheless this is similar to running self defined init scripts.
But at least I have a well defined location to put those fixes into.
Best regards.
Markus
